Title: Improvements in gas analyzing apparatus
IPC: G01N27/16
Filed: 1953-11-13
Abstract: Apparatus for analyzing a gas for two different components comprises two cells 8, 12 each containing a catalytic element connected in a balanceable electric network 21, 22, and arranged to be heated and exposed to the gas, and a generator 9 <PICT:0740436/III/1> <PICT:0740436/III/2> which supplies two different gaseous products, one to each cell, to combine respectively with the two different constituents of the gas.  A sample of furnace flue gas or internal combustion engine exhaust gas, to be analysed for combustible constituents and oxygen, is introduced through pipe 3 via a pressure regulator 5, which may be of the type described in U.S.A. Specification 2,438,973, and is divided into two streams; one stream flows through orifice 7 and mixes with hydrogen from pipe. 11. Elements comprising the orifices 6, 7 are replaceable by elements having orifices of different sizes.  The oxygen and hydrogen are provided by an electrolytic generator 9 (see Group XXXVI).  The cells 8, 12 and the pipes leading thereto are arranged within a metallic housing 4 maintained at constant temperature by heater 18 and thermostat 19.  As shown in Fig. 2 each cell is provided with an insulated base 40 carrying measuring filament 42 and comparison filament 41; shield 43 is divided by partition 44 into two parts, that enclosing the measuring filament being provided with metallic mesh screen 45 and that enclosing the comparison filament with a small aperture 46.  The results of the two analyses may be combined by using a single balanceable electric network as described in U.S.A. Specification 2,420,430, or by providing links 23, 24, actuated by motor M; movement of the link 24 operates pilot control valve 25 and/or indicator 26.  The gas sample regulator 5 comprises a reciprocating part 27 which drops by gravity if the gas flow is interrupted; magnet 28 and armature 29 then actuate switch 31 which operates lamp 32 or a control valve.  The analyser may be modified to analyse two separate gas samples respectively for combustible content and free oxygent content.

Title: Process for the preparation of pure melamine
Filed: 1961-09-04
Abstract: Melamine is obtained from a gas mixture which contains melamine, ammonia, carbon dioxide and solid impurities, by absorbing the mixture in water, removing ammonia and carbon dioxide from the resulting solution by rectification, removing solid impurities, and crystallising and separating melamine from the solution.  The temperature of the solution in the absorption step is preferably kept at approximately 65 DEG C.  After rectification the solution may be clarified by treatment with an absorbing agent e.g. diatomaceous earth, kieselguhr, or activated carbon.  The melamine is preferably separated by crystallisation at below atmospheric pressure.
